Navionics Charts for A50

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Technical Forum John,

Should a Raymarine MFD having internally pre-loaded Navionics Silver cartography be used with a chart card with which it is not compatible, then the MFD may indeed display the pre-loaded Navionics Silver cartography. When used with a compatible Navionics chart card, a Raymarine MFD having internally pre-loaded Navionics Silver cartography will defer to using the cartography stored on the chart card if it has a later publication date that that of the internally pre-loaded Navionics Silver cartography. For geographic areas outside of the coverage area of the compatible Navionics chart card, the MFD will defer to the internally pre-loaded Navionics Silver cartography. Please click here to view a FAQ providing further information on this subject. If the MFD's memory card reader is operational, then it would be recommended that Navionics be contacted to provide a compatible chart card for your MFD.
